Tushbaby v. Fleerose: Design Patent Infringement Case Consolidated into Schedule A Action
Tushbaby, Inc. filed suit against Fleerose in the Southern District of Florida alleging infringement of design patent USD1024542S covering the Tushbaby hip carrier. After 136 days, Judge Leibowitz ordered the case consolidated into a broader Schedule A multi-defendant action targeting multiple online sellers of allegedly infringing carriers.
Tushbaby’s hip carrier design patent enforced via Schedule A consolidation
On June 4, 2024, Tushbaby, Inc. filed a design patent infringement action against Fleerose in the U.S. District Court for the Southern District of Florida, Case No. 1:24-cv-22149, before Judge David S. Leibowitz. The suit centres on USD1024542S (application no. US29/911444), a design patent protecting the ornamental appearance of the Tushbaby hip carrier — a wearable child-carrying device worn at the hip. Tushbaby was represented by Boies, Schiller & Flexner LLP and Slater Legal PLLC, while Fleerose retained the Law Offices of James Liu PLLC.
On October 18, 2024, Judge Leibowitz granted a motion to consolidate this individual action into a parallel Schedule A case, Tushbaby, Inc. v. The Corporations, Limited Liability Companies, and Unincorporated Associations Identified on Schedule A, No. 1:24-cv-21136-LEIBOWITZ. All future pleadings and motions were directed to be filed under that lead case caption. Pending motions in the Fleerose case were denied as moot, with leave to refile in the consolidated proceeding.
The 136-day timeline to consolidation is consistent with Tushbaby’s broader litigation strategy of pursuing multiple online sellers simultaneously through Schedule A actions — a common enforcement mechanism against e-commerce defendants. The public record for this individual docket is silent on whether any substantive merits rulings or settlement discussions occurred before consolidation, and the ultimate outcome for Fleerose will be determined within the lead multi-defendant proceeding.

What consolidation into a Schedule A action means for both parties
Consolidation merges cases sharing common questions of law or fact
Under Federal Rule of Civil Procedure 42(a), a court may consolidate actions involving common questions of law or fact. Here, Judge Leibowitz merged this individual Fleerose action into a Schedule A lead case targeting multiple online sellers of allegedly infringing hip carriers. Consolidation does not resolve the merits — it streamlines pretrial and trial proceedings under a single docket.
FRCP 42(a) consolidationFleerose now litigates as one of multiple Schedule A defendants
By being folded into the Schedule A action, Fleerose’s individual case number is administratively closed. Fleerose must now respond, file motions, and potentially negotiate within the framework of the lead multi-defendant case. This can dilute individual leverage but also means any injunction or default judgment obtained in the lead case may apply to Fleerose directly.
Multi-defendant Schedule ATushbaby gains procedural efficiency across all Schedule A defendants
Consolidation allows Tushbaby to pursue uniform relief — including temporary restraining orders, asset freezes, and permanent injunctions — against all named defendants in a single proceeding. Discovery, claim construction, and any trial would proceed once for all defendants, significantly reducing Tushbaby’s litigation costs compared to maintaining separate dockets against each seller.
Enforcement efficiencySchedule A tactics signal aggressive design patent enforcement in e-commerce
Tushbaby’s use of Schedule A actions — listing multiple anonymous online sellers as defendants — is a recognised enforcement pattern against marketplace infringers on platforms such as Amazon and AliExpress. Consolidation reinforces the patent holder’s ability to obtain broad injunctive relief efficiently. Online sellers of competing hip carrier products should treat this as a signal that USD1024542S is being actively enforced.

Official order — verbatim text
The consolidation order is procedural rather than substantive — Judge Leibowitz made no ruling on infringement, validity, or damages. The direction that all pending motions are denied as moot and must be refiled in the lead case signals that Fleerose’s substantive position resets within the consolidated proceeding. The outcome for Fleerose on the merits remains entirely open and will be determined under docket No. 1:24-cv-21136.
USD1024542S — Tushbaby hip carrier ornamental design
USD1024542S (application no. US29/911444) is a U.S. design patent protecting the ornamental appearance of the Tushbaby hip carrier — a wearable device that allows caregivers to carry infants and toddlers on the hip. Design patents protect the way a product looks rather than how it functions, granting the holder the right to exclude others from making, using, or selling products with a substantially similar ornamental design. The application number US29/911444 follows the standard USPTO design patent numbering convention.
For baby and toddler product companies, USD1024542S represents a direct enforcement risk in the wearable carrier category. Tushbaby’s decision to pursue multiple Schedule A defendants simultaneously — including Fleerose — confirms the patent is being actively asserted against e-commerce sellers. Any company designing or sourcing hip-seat carriers for sale on Amazon, Walmart Marketplace, or similar platforms should conduct a design clearance review against this patent before commercialisation.
Should you run an FTO against USD1024542S?
Any company developing, importing, or selling hip-seat child carriers — particularly those distributed through e-commerce marketplaces — should treat USD1024542S as a live enforcement risk. The active Schedule A litigation in S.D. Florida demonstrates Tushbaby’s willingness to pursue multiple defendants at once. Product teams sourcing carriers from overseas manufacturers are especially exposed if the ornamental design resembles the Tushbaby form factor.
PatSnap Eureka’s FTO Search Agent can cross-reference your product design against USD1024542S and related design applications in Tushbaby’s portfolio, flag prosecution history and continuation risk, and surface prior art that may support a validity challenge. Running a design freedom-to-operate analysis before product launch is materially less costly than defending a Schedule A action with an accompanying asset freeze.

What this case signals for the baby products IP landscape
Tushbaby’s Schedule A strategy demonstrates how design patents can be weaponised against e-commerce marketplaces at scale.
Design patents are powerful tools against online marketplace infringers
USD1024542S covers the ornamental design of the Tushbaby carrier — a relatively narrow but commercially potent right. Design patent infringement requires only that an ordinary observer would find the designs substantially similar. This lower threshold makes design patents particularly effective in Schedule A e-commerce enforcement where defendants sell near-identical copycat products.
Schedule A consolidation reduces per-defendant litigation cost for patent holders
By consolidating Fleerose and other defendants into a single lead case, Tushbaby achieves claim construction, discovery, and injunctive relief in one proceeding. Competitors and sellers in the baby carrier space should note that this approach has been upheld in the Southern District of Florida and is replicable across similar design patent portfolios.
Tushbaby v Fleerose — key questions answered
Judge Leibowitz consolidated Case No. 1:24-cv-22149 into lead Schedule A case No. 1:24-cv-21136 on October 18, 2024. No merits ruling was issued. All pending motions were denied as moot, with leave to refile in the consolidated proceeding. The case concerned alleged infringement of design patent USD1024542S.
USD1024542S (application US29/911444) is a U.S. design patent protecting the ornamental appearance of the Tushbaby hip-seat carrier. It matters for competitors because design patent infringement is assessed under the ordinary observer test — a relatively plaintiff-friendly standard — and Tushbaby is actively asserting it against multiple e-commerce sellers through Schedule A litigation.
Schedule A cases allow a plaintiff to sue multiple online marketplace sellers under a single complaint by listing defendants pseudonymously on a schedule. They are common in S.D. Florida for e-commerce IP enforcement. Courts frequently grant ex parte TROs and asset freezes against Schedule A defendants, making them a powerful — and controversial — enforcement tool.
Consolidation does not resolve Fleerose’s liability. It means Fleerose’s individual docket is closed and all future proceedings occur in the lead case No. 1:24-cv-21136. Fleerose remains a defendant and must refile any pending motions. The merits of the infringement claim — and any damages or injunctive relief — will be determined in the consolidated proceeding.
Tushbaby was represented by Boies, Schiller & Flexner LLP and Slater Legal PLLC, with attorneys Eric J. Maurer, James Murray Slater, and James W. Lee on record. Fleerose was represented by the Law Offices of James Liu PLLC, with attorney Jianyin Liu appearing for the defendant.
